Monique randomly surveyed 30 students from

Naily [24]

Answer:

522

Step-by-step explanation:

Find the percent of students in her class that have a dog or cat:

Set up a proportion: $\frac{18}{30} = \frac{x}{100}$
Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
So, 60% have a dog or cat

Find 60% of the total amount of students in Monique's school:

60% of 870 = $\frac{60}{100}$ × $\frac{870}{1}$
$\frac{60}{100}$ × $\frac{870}{1} = \frac{52200}{100}$
$\frac{52200}{100} = \frac{522}{1} = 522$

I hope this helps!

Jeanine Baker makes floral arrangements. She has 11 different cut flowers and plans to use 7 of them. How many different selecti

Alex Ar [27]

Answer:

<h2>330 different possible selections are there.</h2>

Step-by-step explanation:

There is a total of 11 cut flowers.

Jeanine Baker has to choose 7 flowers among the 11 flowers.

The formula for choosing r numbers from n numbers is defined by $^{n}C_{r} = \frac{n!}{r!\times(n - r)!}$ , n > r.

From 11 flowers 7 flowers can be chosen in $^{11} C {7} = \frac{11!}{7!\times4!} = \frac{8\times9\times10\times11}{2\times3\times4}.$ = 330 ways.

There are 330 possible ways to choose 7 flowers from 11 flowers.

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an

NeX [460]

Answer:

$6400\ \text{N}$

Step-by-step explanation:

$\dfrac{m}{t}$ = Mass flow rate of water = 320 kg/s

$m$ = Mass of water on the door

$t$ = Time

$v$ = Velocity of water on the door = 20 m/s

Force is given by

$F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}$

The average force is exerted by the stream of water is $6400\ \text{N}$ .

what is the smallest of three consecutive integers i the sum of the smaller two integers is two more than seven times the larges

NNADVOKAT [17]

Answer:

The numbers that meet these conditions are -3, -2 and -1.

This means that the wording of the question is somewhat ambiguous:

The <em>lowest</em> of the three numbers is -3.

The <em>smallest</em> however is -1.

You may need clarification on which of those is being asked for.

Step-by-step explanation:

Let's call those numbers a, b and c, with a the smallest and c the largest. We're told two key things here:

1) The sum of the smaller two integers is two more than seven times the largest integer. In other words a + b = 7c + 2

2) We're looking for three consecutive integers, which means that we can define them with a single variable. If the smallest one is a, then the others are a + 1 and a + 2.

We can take those and put them together, giving us the equation:

a + (a + 1) = 7(a + 2) + 2

Which we can then solve for a:

a + (a + 1) = 7(a + 2) + 2

2a + 1 = 7a + 14 + 2

2a - 7a = 14 + 2 - 1

-5a = 15

a = -3

Since a is -3 and also the smallest, we can then say that the numbers are -3, -2 and -1.
